CY7C65642-28LTXCT

Controllers Overview

The CY7C65642-28LTXCT is a USB 2.0 hub controller from the EZ-USB™ HX2VL family, featuring four downstream ports with dedicated transaction translators for high performance. It operates within a voltage range of 3.15 V to 5.25 V and supports data rates up to 480 Mbit/s. The device integrates an internal regulator requiring a single 5 V supply, though external regulation is supported. It includes a 2K ROM and 64-byte RAM MCU, supports bus-powered and self-powered modes, and functions in temperatures from 0°C to +70°C.

Controllers Feature Summary

• Integrates four downstream ports with independent transaction translators to maximize bandwidth efficiency.
• Features highly integrated design with built-in regulators, pull-up/pull-down resistors, and termination resistors to reduce bill-of-material costs.
• Supports configurable VID/PID and port settings via external EEPROM or pin strapping.
• Includes internal power failure detection for ESD recovery and overcurrent protection management.

Controllers Applications

• Docking stations
• Standalone hubs
• Monitor hubs
• Multi-function printers
• Gaming consoles

Controllers Procurement Notes

Verify the specific suffix 'CT' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required package type and temperature grade for the intended application environment.

Controllers Selection Notes

Select this component for designs requiring low-power USB 2.0 connectivity with multiple downstream ports. Consider the 28-pin QFN package for space-constrained layouts. Evaluate the need for external versus internal power regulation based on system power budget and board layout constraints.

Controllers Part Context

This part belongs to the EZ-USB™ HX2VL series, which focuses on very low-power consumption for USB hub applications. It serves as a successor to previous generations like the HX2 and HX2LP, offering improved power efficiency while maintaining full USB 2.0 compliance and high-performance transaction translation capabilities.

Controllers Replacement Considerations

Consult application note AN69235 for migration details from EZ-USB™ HX2 and HX2LP families. Verify pin compatibility and software driver updates when transitioning from older hub controller models to ensure seamless integration into existing hardware designs.
